The Xishuangbanna Tropical Botanical Garden is a plant research station of the Chinese Academy of Sciences, located in Southwest China's Yunnan province. Now 60 years old, the garden fosters over 13-thousand species of plants in its more than 30 living collections. Let's now take a look at one of the most diverse botanical gardens for outdoor plants in the world.

LIU GUANGYU XISHUANGBANNA TROPICAL BOTANICAL GARDEN "I'm Liu Guangyu. I'm an environment educator in Xishuangbanna Tropical Botanical Garden. I've been here for ten years as an environmental educator. My job is to introduce these amazing tropical plants to publics. People love flowers and flowers are colorful, beautiful and very attractive to the publics. So we build a garden with the metals, with the flowers, so publics just like to walk in."

RICHARD CORLETT XISHUANGBANNA TROPICAL BOTANICAL GARDEN "My name is Richard Corlett. I was born in London. Here I'm a professor in Xishuangbanna Tropical Botanical Garden. I've been here for seven years. Xishuangbanna has about the third of the mammals and birds in China and about 50% of the plants. And Yunnan has more than half of the species in China."

LIU GUANGYU XISHUANGBANNA TROPICAL BOTANICAL GARDEN "We've built a palm garden. Palm garden is also a very attractive one for the public because palm is like a culture exotic thing. Another one is the rain forest. The rain forest is one of the target places for most of the tourists. It's a very new experience for most of the Chinese people because we are living in the temper areas."

RICHARD CORLETT XISHUANGBANNA TROPICAL BOTANICAL GARDEN "This is an important place for conservation. Plants are the basis of Chinese civilization. You eat plants to the three meals. Today you're wearing plants. China's based on plants. This is extremely important and this knowledge is continuely updated."

LIU GUANGYU XISHUANGBANNA TROPICAL BOTANICAL GARDEN "Right now in China we have a strong trend or motive to learn about nature because of the people and kids are living in cities right now in China. We got 'nature education'. So a lot of parents spend a lot of money for the kids to walk out of the classroom into the nature."

RICHARD CORLETT XISHUANGBANNA TROPICAL BOTANICAL GARDEN "We just decided we should set a target of 'zero extinction' for nature's plant species in Xishuangbanna. There're about 4,000 native plants and we assess data of all of these. So this took us four or five years. Some of them we still haven't found."

LIU GUANGYU XISHUANGBANNA TROPICAL BOTANICAL GARDEN "We're very confident about this work. Very meaningful, very valuable. We just follow us in hearts to do better."
